Episode 1: Should you tell if you cheated?

I received an email not too long ago from a reader who asked:

I cheated on my husband. It wasn't a one-time thing, but it's over now. I'm wracked with guilt, but I also know that if I tell my husband, it will destroy him. But I also feel like I should be honest and like I'm keeping a terrible secret, even though I actually feel closer to him now than ever. What should I do? This is certainly a complicated issue many of us have faced. There's a spark of attraction with someone new. Things haven't been quite "right" in your marriage for a long time, and you get swept away in a moment. Or two, or three... Now you're left with the question: should you tell your husband? Here's my take on this, shared by the always awesome Dan Savage, and I'll warn you, it's a bit controversial, and not a perspective shared by everyone.
